Abstract
A head-up display system comprises a microprojector, first and second viewer optics, a redirection optic, and an electronic controller. Switchable electronically between first and second optical states, the redirection optic is configured to receive a display image from the microprojector, to convey the display image, in the first optical state, to the first viewer optic, and to convey the display image, in the second optical state, to the second viewer optic. The electronic controller is configured to, during a first interval, switch and maintain the redirection optic in the first optical state and cause the microprojector to form the display image based on first image data. The electronic controller is further configured to, during a second interval, switch and maintain the redirection optic in the second optical state and cause the microprojector to form the display image based on second image data.
